SAFETY-RAZOR.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed 0am: 8.1907. Serial No. 396,368.

To all whom it may concern:

Be it known that I, PHILIP K. STERN, a citizen of the United States, residing in the city of New York, in the county and State of New York, have invented certain new and useful 'Im rovements in Safety-Razors, of which the ollowing is a specification.

My invention in safety razors relates to certain new and useful improvements in that type of safety razors embodying a flat blade and a guard adapted to the edge of the blade to prevent the latter from accidentally abrading or cutting the skin.

t has particular reference to the means for retaining the blade in contact with the guard and also to the construction of the guard and frame for holding the blade, and the object of my invention is to provide a of the guard and frame-work which carries the razor blade than any of those constructions at present in vogue and previous to my invention in so far as am at present aware.

The features characteristic of my inven tion are depicted in the drawings hereto attached which form a part of. this specification ahd are referred to in the descriptive matter thereof relative thereto and the distinct features of novelty are more particu-- With reference to the drawings :'Figure 1 is a front elevational view of my improve safety razor illustrating certain parts of the frame-work in dotted lines. Fig. 2 is a top lan view of a still somewhat greater enargement of the frame-work illustrating the blade in broken lines andlthat portion of the frame-work gripped by the ferrule in dotted lines. Fig. 3 1s a vertical end elevational view of the ferrule and a section of the blade and frame-work taken on ,the lines 3-3 of Fig. 1, and Fig. '4 is a front vertical sectional elevational view of the ferrule takenon the lines 4-4 of Fig. 3 omitting the blade.

In the several figures, similar characters of larly pointed out in the claims.

reference are employed to designate likev parts throughout where they occur, wherein,

A depicts the blade of my improved safety razor which is obtained from preferably a flat strip or ribbon of razor steel and of a thickness commonly referred to as wafer blades and B constitutes the guard therefor which is preferably formed into shape from a suitable length of sufficiently resilient wire to provide the several crimps and loops respectively; 3', 9' 1' 'i, g, 9', 9' 9' and a b c at one terminal. and c b a at the opposite thereto of the guard B.

C indicates a split ferrule which will be hereinafter referred to as a socket. This is composed of a strip of spring sheet metal bent into the form of a cylinder into which the upper terminal of the handle D is thrust.

The principle of the invention is involved in the action of the crimped or sinuously formed metallic guard B provided with the terminal loops 0, b c and c l) a for gripping the corners of the blade at the edge and opposite ends thereof, at diametrically opposite ends of the guard, together with a clip d extending from the ferrule or socket C, whereby the blade A is engaged and held in ositionby virtueof the yielding properties 0 the spring resulting from the crimped formation of the guard B, and the elasticity ofthe socket or ferrule C. In practice I prefer to construct the guard B of wire having a sufficient amount of spring to enable the terminal loops 0. b c and c l) a to be'disengaged from the corners of the blade so asto enable the blade to be removed while theguard B,in the meanwhile retains its form and such that upon the extension of the frame thereafter in the act of inserting the blade, there will be sufficient spring in the wire and ferrule C to force the abutments aa at the opposite terminals of the guard into engagement with the ends of d the blade A, while at the same time, the abutments will force the blade by its edge against the inclined surface E of theclip dthereby firmly binding the blade A against lateral ortransverse motion due to strains imposed upon the same in the act of shaving.

As will be observed more particularly with reference to Fi 2 the opposite terminals of the guard B, w ere the corners of the blade are engaged by the loops a b c and c b a, the abutments a and a. respectively forming arts of these loops engage the ends of the blade while the portions 1) and b res ectively engage the upper surface of the bla e to revent lifting and the remaining portions 0 the loops 0 and c constitute abutments which provide for the backing of the blade a ainst the clip d as aforesaid, while the turne over ort ion e of the clip d holds the blade down in contact with the frame-work, thus firmly securing and maintaining the position of the bladeA in the frame or holder.

The crimped portions extending upward against the edge of theblade between the portions 7', j, and j, and j, andq' and respectively are arranged so as to lie in a plane. substantially parallel to the ferrule or socket C, thus making an angle with the blade as illustrated in Fig. 3, and the portions i-i of the frame or guard are secured by their an gular limbs h-h to the clips f-f respectively by bending the latter securely around them.- The clips ff are turned over and inwardly at the upper edge of the ferrule O on a line at an angle of about degrees'from the horizontal and to ether with the limbs 'i'i/with the guard B eect the inclination of the blade toward the handle whereby the an ular position of the blade against the sur ace to be shaved is insured.

The frame consisting of the guard B and socket C as will be observed by the foregoing description possesses sufiicient flexibility to 'not only provide for the insertion and withdrawal o the blade A but in addition possesses a sufficient amount of elasticity to clamp a slightly smaller blade or one in excessof the normal. This desideratum is of particular importance when dull blades are to be exchanged for others which may vary somewhat in dimensions.

For compactness particularly when my improved safety razor is to be carried in the pocket, I detach the handle D from the socket C and dispose the same longitudinally of the blade A at the underneath side thereof against the limbs 01-?) of the guard B, whereupon the'same may be placed in a compact retaining case or receptacle.

It Wil be observed in Figs. 2 and 3, that the cuttingedge of the blade extends somewhat over the center of the cylindrical surface of the wire of which the guard B is composed at' the summit of the crimped portions.

Having fully described my invention I claim as new and desire to secure by Letters Pat'entof the United States. i
